Vivid new colors, typography, and edge-to-edge imagery help to focus your attention

Notifications

New ways to control when and how you receive messages – only get interrupted when you want to be

View and respond to messages directly from your lock screen. Includes the ability to hide sensitive content for these notifications

For fewer disruptions, turn on Priority mode via your device’s volume button so only certain people and notifications get through. Or schedule recurring downtime like 10pm to 8am when only Priority notifications can get through

With Lollipop, incoming phone calls won’t interrupt what you’re watching or playing. You can choose to answer the call or just keep doing what you’re doing

Control the notifications triggered by your apps; hide sensitive content and prioritize or turn off the app’s notifications entirely

More intelligent ranking of notifications based on who they’re from and the type of communication. See all your notifications in one place by tapping the top of the screen

Battery

Power for the long haul

A battery saver feature which extends device use by up to 90 mins

Estimated time left to fully charge is displayed when your device is plugged in

Estimated time left on your device before you need to charge again can now be found in battery settings

Security

Keep your stuff safe and sound

New devices come with encryption automatically turned on to help protect data on lost or stolen devices

SELinux enforcing for all applications means even better protection against vulnerabilities and malware

Use Android Smart Lock to secure your phone or tablet by pairing it with a trusted device like your wearable or even your car

Device Sharing

More flexible sharing with family and friends

Multiple users for phones. If you forget your phone, you still can call any of your friends (or access any of your messages, photos etc.) by simply logging into another Android phone running Lollipop. Also perfect for families who want to share a phone, but not their stuff

Guest user for phones and tablets means you can lend your device and not your stuff

Screen pinning: pin your screen so another user can access just that content without messing with your other stuff

New Quick Settings

Get to the most frequently used settings with just two swipes down from the top of the screen

Connectivity

Improved network handoffs resulting in limited interruption in connectivity. For example, continue your video chat or VoIP calls without interruption as you leave the house and switch from your home Wi-Fi back to cellular

Improved network selection logic so that your device connects only if there is a verified internet connection on Wi-Fi
